Description

Ethyldimethyl(9-Octadecenyl)Ammonium Bromide is a quaternary ammonium salt (quat) surfactant with a long-chain oleyl group, offering a unique combination of cationic activity and hydrophobic character. This compound is valued for its potent antimicrobial, antistatic, and conditioning properties, making it a versatile functional ingredient. It is primarily needed by manufacturers in the personal care, textile, and industrial biocides sectors for formulating effective and stable products.

Application

• Hair Conditioners & Cream Rinses: Acts as a primary cationic surfactant, providing excellent detangling, softness, and manageability to hair by neutralizing static charge.
• Fabric Softeners: Imparts a soft, fluffy hand feel to textiles and reduces static cling in dryer sheets and liquid softeners.
• Industrial & Institutional Biocides: Serves as an active ingredient in disinfectant and sanitizer formulations for hard surfaces, leveraging its bactericidal and fungicidal activity.
• Antistatic Agents: Used in plastics, coatings, and synthetic fiber processing to dissipate static electricity and prevent dust attraction.
• Emulsifier & Dispersant: Facilitates the formation and stabilization of oil-in-water emulsions in various cosmetic and industrial preparations.
• Phase Transfer Catalyst: Enhances the rate of reactions between reactants in different phases in organic synthesis.
